The eruption hurled a coronal mass ejection toward NASA's STEREO-B spacecraft. Analysts at the Goddard Space Weather Lab have prepared a forecast track showing the progress of the cloud. No planets are in the line of fire.

Stay tuned for updates as the sun turns to reveal the active region in the days ahead.www.spaceweather.com
